I will list it here now. This list counts only active player in the ladderboard. 05.09.2019
What you can see is:
Most played random modus is 4vs4 > 3vs3> 2vs2 > 1vs1
Also that Wehrmacht and okw is always mosted pick. In the middle is soviet; and brit and USA is less.
Why for Premade AT does not count this numbers?!
1. Reason is, that many teamgame players are playing often in new combinations. But they need to play 10 games with the same 4 players, to get shown up here. Thats why the AT 4vs4 numbers are so low.
2. Many 2vs2 AT premade are seachring 3vs3, 4vs4 too.
